To extend your car copyright in Pattaya, visit the local Department of Land Transport (DLT) office (DLT) with your copyright, visa, work permit/residency certificate, medical certificate (from a clinic, valid 1 month), your current license, and fee; complete vision/reaction tests and a video orientation, then pay and get your photo taken for a 5-year renewal, but ensure your visa type (1-year or longer) supports a 5-year license. Book an appointment via the DLT website to check here avoid long waits. You can also use a private agency in Pattaya, such as Pattaya4all which can assist with document preparation and navigating the process for a fee.
